The lower attached tothe inside of the bottom of the ends of these bars normally rest uponthe top 50 cylinder, so as to engage the ratchet-teeth, is of the plate11, and near the lower end each I00 bar has a horizontal mortise 35,Fig. 5. In an outwardly-opening slot in each bar the end of a thinradial plate 36 is fastened. These plates are adapted to receive thebooks, gagestops 37 being provided to determine the positions of thebooks on the plates and holdingfingers 38 being pivoted to the sides ofthe plates, so that they may be placed against the books, as indicatedby the dotted lines in Figs. 2, 4, and 5 of the drawings, to prevent theoutside leaves of the books from opening out when the plate is loweredand from curling open when tipped or pasted on and to prevent stickingof deckel edge leaves. As the fingers are pivotally attached to theplates when the book is raised, the pasting mechanisms push the fingersdown out of the way to the positions illustrated by the full lines inFigs. 2, 4, and 5.

A lever 39, having one end pivoted to the inside of the front frame ofthe machine and oscillated by a cam 40 on the cam-shaft,is connected bya link 41 with a verticallymovable slide 42, attached to which is aforwardly-extending arm 43, the same as shown and describedin thepatent, No. 690,959, previously referred. The front end of the arm 43 isattached to a bar 44, that is movable vertically in a mortise in theinside of the front frame of the machine, Fig. 4. The upper end of thisbar has a mortise 45 in sucha location that when the bar is raisedthrough an opening in the plate 11, on which the bars 33 normally rest,the mortise is adapted to receive the lower end of one of theverticallymovable plate-bars carried by the cylinder, Fig. 4. Theelevating-cam is timed to raise the lever and arm with the bar upwardlyinto such position that when the cylinder is rotated the lower end of aplate-bar enters the mortise in the upper end of the elevating-bar, andthe stop-bolt and shoulder are timed to stop the cylinder with the barsthus engaged and forming practically a single piece. After thisengagement has been completed, the elevating-cam lowers the arm and theengaged bars, with the attached plate and the book which the platesupports. After the book has been lowered and the paste-boxes 46, Fig.1, have been brought together by such mechanisms as are shown in theprior patent the cam raises the arm and bars and carries the book upbetween the paste-boxes. Vhen the book has been lifted way up, thestop-catch is drawn down and the cylinder given a partial rotation,carrying the book which has been pasted and thrust into its case aroundto one side, where that book may be removed and the following plate,with another unbound book, is carried into the position where the barsare locked, so as to be lowered and raised by the next movement of theelevating mechanism.

An operator places an unbound book upon the plate that projectsforwardly from the cylinder, and when the cam and lever and rack andpinion cause the ratchet and pawl to rotate the cylinder that plate,with the unbound book, is turned toward the back over the openingbetween the paste-boxes, and the plate-bar is engaged with theelevating-bar. When the parts are in these positions, the stop-bolt isdrawn up and engages a stopshoulder, so that the cylinder will hold inexact position. The elevating-cam then causes the arm and engagedelevating and plate bars to lower and raise the plate, with the unboundbook between the paste-boxes. As the plate is being lowered and raisedin the machine an unbound book is placed upon the plate which isprojecting toward the front. After the plate and book have been raisedthe cylinder is released and rotated, so that the plate, with thelast-placed unbound book, is carried over the paste-boxes, and thepasted book is carried toward the front. While an unbound book is beinglowered and raised, the bound book is removed from the plate that hasturned to the front and another unbound book is adjusted on the platethat is to be turned toward the back. The machine may be run rapidly,and yet the operators have sufficient time to remove the bound book andproperly adjust an unbound book while a book is being bound.
